BUILDING-BLOCK.

No. 859,764. I

Specification of Letters Patent.

Patented July 9, 1907.

Application filed January 29. 1906. sssrno. 298,518.

Toolt whom it may concern:

Be it known that I, Lns'rnn W. HAGERMAN, a citizen of the United States,residing at Orchard, in the county of Antelope and State of Nebraska,have invented certain new and useful Improvements in Building-Blocks, ofwhich the following is a specification.

The object of my invention is to provide an improved I construction ofcement or concrete block to be used for building purposes and soconstructed and arranged that it will produce a moisture proof and waterproof wall and which will be light without detracting from itscharacteristics of rigidity and stability, and which may be readilyhandled and hauled without danger of breakage.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result, reference is to be had to the followingdescription and accompanying drawings, in which: 1

'Figure 1 is a perspective view of several building blocks embodying myinvention. Fig. 2 is a similar view of one of said blocks showing it incondition for hauling and handling. Fig. 3 is a longitudinal sectionalview. Fig. 4 is a transverse sectional View. Fig. 5 is a horizontalsection of a portion of one of the blocks, on a reduced scale. Fig.6 isa detail perspective view of one form of tie that may be employed.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

My improved building block may be formed of cement or concrete .or anyanalogous material and preferably consists of one piece or integralstructure of oblong shape as ordinarily employed in buildingconstructions, but not necessarily of such shape. It comprises twosections or members 1 provided with fiat top and bottom edges 2 and 3respectively, and connected together by means of laterally extendingnibs or wings 4, preferably two in number and located near one end ofthe entire block. In each of these connected wings 4 there is embedded apreferably metallic plate 5 which may be of zinc or any other desiredmoisture proof metal or material and is preferably of such material asto be pliable without danger of breaking. Each plate 5 is provided withan opening or slot 6 located entirely with its margin and through whichthe preferably metallic tie 6 extends as shown best in Figs. 4 and 5.The tie is-designed to effectively secure the two sections or members ofthe block together as well as to fill the slot 6 and prevent moisturefrom passing therethrough from one section of the block to the oppositesection and in the construction of the tie shown in the said viewsreferred to the tie 6 is provided with one or more apertures 6 throughwhich the concrete may extend. Or as shown in Fig. 6- the tie mayconsist of a II-shaped member 9 the ends 10 of which are designed toextend through the slots 6 in the metallic plate.

they extend beyond the side edges of the wings and also both above andbelow the same The laterally extending and connected wings 4,01 the twosections or members of the block, produce in the completed block two endair spaces 7 and a middle air space 8 which is bound. on either side bythe wings 4. In a wall, where my improved blocks are laid end for end itwill of course be understood that the end air spaces 7 are also closedby the abutting ends of the blocks. The middle air space 8 is in thepreferred proportion of the parts, approximately twice long as the endair spaces 7 plus the width. of the wings-so that when the blocks arelaid one upon the other in the usual staggered or alternate arrangementemployed in building constructions the zinc or other spacing plates 5 oftwo adjoining blocks are intended to be within the central air space ofthe overlapp ng block just. above. Hence the mortar will be divided, andthe plates will not be bent down by the pressure of the block laid ontop.

In the manufacture of my improved building block, it is preferred toembed the spacing platcs 5 in the coment or concrete and form the blocksat one and the same operation, whereby there is produced a singleintegral structure which Will possess a maximum of rigidity orstability. As the spacing plates 5 are of zinc or some other metal ormaterial which possesses sufficient pliancy to permit of being bentwithout breakage and yet sufficiently stiff to withstand accidentalbending and be self sustaining I prefer to bend the projecting upper andlower ends of the plates down upon the respective top and bottom edgesof the blocks when the blocks are initially formed so that the blocksmay be hauled from place to place and handled Without danger of injuryto the said plates. It is to be understood however that these plates arestraightened at their up per andlower ends so that such ends willproject in the manner before described preparatory to placing the blocksone upon another to form a wall.

From the foregoing description in connection with the accompanyingdrawings it will be seen that I have provided an improved constructionofcement or concrete block which embodies one integral structure havingoffset portions or wings that are connected together to produce twolongitudinally extending sections or members with air spaces betweenthem, the said wings or offsets having embedded therein zinc or otherplates that project both above and below the flat edges of the block andproject into the said air spaces of other blocks. Hence there are nomortar connections between the outer and inner walls or sections of theblocks, and a completed wall that has been built with my improved blockwill, it is manifest, be practically constructed with an outer portionhaving no mortar connection with the inner portion,- said two portionsbeing spaced from each other with air spaces and the said zinc plates 5so that moisture will be precluded from entering through the intersticesbetween the blocks.

Having thus described the invention what is claimed as new is:

1. A block of the character described, comprising two,

longitudinal sections or members provided with olaet connected wingswhereby to produce air spaces between said sections and pliable andselfsustained plates embedded in said wings with their ends projectingabove the said sections, whereh'y when the said blocks are laid incourses with an alternate arrangement, the projecting ends 0! the saidplates will extend into thenir spaces 0! the blocks above and preventmoisture from the wet mortar irom passing over one sectionot the blocksto the opposite section;

2; -A block of the character described, provided with air spaces andwith embedded moisture proof plates of pliable material that projectabove the upper plane of the bloclr and are designed to enter the airspaces of similar blocks above, the material of which said plates'areformed being such that the projecting portions of the plates will besell-sustaining, as and for the purpose set forth.

in testimony whereof I a'flix my signature in presence of two witnesses.
